Problems solved by technology

[0003] is mainly used in transparent plastic film, sheet or board. In a humid environment, when the humidity reaches below the dew point, a layer of fine water droplets will condense on the surface. The surface is blurred and fogged, which hinders the transmission of light waves. For example, when packaging products with film, the contents will also be invisible due to fogging, and the generated mist droplets will easily cause rot and damage to the contents.

Embodiment 1

[0014] An antifogging agent for automobile glass, characterized in that it contains the following ingredients in weight percentage: 16-20% sorbitan monostearate (S-60), 2-5% methyl trifluoropropyl silicone oil, Sorbitan monopalmitate (S-40) 14-18%, volatile perfluorinated oil 2-5%, 1,5-pentanediol 2-5%, sodium benzoate 0.5-2.5%, deionized water 45% -65%.

[0015] Instructions:

[0016] Wipe the windshield clean first, then spray the defogger on it, let it dry for 1-2 minutes, and then wipe it clean with a dry towel. In this way, a transparent protective film will be formed on the glass, which can effectively prevent water vapor from condensing on the glass to form a fog layer. Generally, spraying once can prevent fog for about a week. It will be better to use it before the fog is formed in the car. Sometimes, after the wiper is started, a proper amount of the present invention is sprayed on the windshield outside the car, the oil film and dirt on the glass will be scra...

Abstract

The invention relates to an antifogging agent and especially relates to an automobile glass antifogging agent. The automobile glass antifogging agent comprises, by weight, 16-20% of sorbitan monstearate (S-60), 2-5% of methyltrifluoropropyl silicone oil, 14-18% of sorbitan monopalmitate (S-40), 2-5% of volatile perfluoro-oil, 2-5% of 1, 5-pentanediol, 0.5-2.5% of sodium benzoate, and 45-65% of deionized water. The automobile glass antifogging agent has excellent hydrophobicity and antifogging function, can prevent a high temperature, can improve dirt resistance, can prolong antifogging time, can improve antifogging effects, and has a wide use range, a low cost and no side effects on the human body. Through coating automobile outer glass and rearview mirrors, the automobile glass antifogging agent has effects of preventing rain, cleaning glass and protecting a wiper. The automobile glass antifogging agent can be dissolved in water, has no easy combustion and blast risk and is portable.

Description

technical field [0001] The invention relates to an antifogging agent, in particular to an antifogging agent for automobile glass. Background technique [0002] The anti-fogging agent adopts dispersed anti-dripping materials and nano-organic active agents. The surface of the glass treated with anti-fogging agent has a layer of super-hydrophilic nano-film, which makes the mist vapor contact with it to form a low-freezing-point mixture to prevent fogging. The maintenance time can be up to 15 days. And non-toxic, no smell, no corrosion. [0003] It is mainly used in transparent plastic films, sheets or plates. In a humid environment, when the humidity reaches below the dew point, a layer of fine water droplets will condense on the surface, making the surface blurred and atomized, hindering the transmission of light waves. For example, using When the product is packaged in film, the contents will also be invisible due to fogging, and the generated fog droplets will easily ...
